IRON FILING.

To'all 'whom V1f may concern.'

Be it known that I, FRANZ WIEDER, re siding at Bliersheim, Germany, a subject of the Emperor of Germany, have invented a certain new and useful Improvement in Iron Filings, of which the following is a specification.

The subject mattei' of the present inven tion is an iron piling combining necessary strength with simplicity in manufacture and which by joining a piling to the next one, will produce a very sure joint.

In the drawing is illustrated Figure l a cross section of a piling wall, in which thel piles are formed in accordance with this invention; and Fig. 2 a cross section of a single pile.

In order to produce an iron pile, a bar of cross 'shaped cross section is first rolled out in the usual manner, having four shanks the two neighboring shanks of which A, being 0f the same length and slightly longer than the two other shanks A1. The two longer Shanks A will thereupon be finished-rolled in such a manner that their free ends will be turned inward and bent so that hook shaped flanges a2 will be produced. As shown in the drawing the measurement has been so selected that the distance measured between the inside of the flanges a2 and the other shank A, also provided with a flange n.2 is approximately equal to the length of the shorter shank A1 with the addition ot the thickness of the wall. The iron piles may be therefore joined together, each iron pile with its two flanges a? inclosing the two shorter shanks Ai of the neighboring pile, forming a secure guid, as'will be evident from the drawing.

I claim:

1. A cross shaped pile having two pairs of longitudinal blades, one pair of which forming a female member and the other pair a male member.

2. A cross shaped pile having two pairs of longitudinal blades, one pair of which forming a female member and the other pair a male member; said pairs of blades being oppositely disposed to each other on each side of a central plane and their blades forming continuations of each other.

3. A cross shaped pile having two pairs of longitudinal blades, one pair of which forming a female member and the other Specification of Letters Patent.

pair a male member; the female pair of blades having inwardly bent anges.

4. A cross shaped pile having two pairs of longitudinal blades, one pair of which forming a female member and the other pair a male member; the female pair of blades having inwardly bent flanges; said pairs of blades being oppositely disposed to `each other on each side of a central plane and their blades forming continuations of each other.

5. A cross shaped pile having two longer and two shorter longitudinal blades, the two longer blades being provided with flanges bent toward each other.

6. A cross shaped pile having two longer and two shorter longitudinal blades, the two longer blades being provided with flanges bent toward each other at approximately right angles.

7. A cross shaped pile having two longer and two shorter longitudinal blades, the two longer blades being provided with flanges bent toward each other, the two longer blades situated to one side and the two shorter blades to the other side of the pile, whereby said longer blades are adapted to securely engage the shorter blades of the adjoining pile when built up to form a wall.

8. A cross shaped pile havingtwo longer and two shorter longitudinal blades, the two longer blades being provided with flanges bent toward each other at. approximately right. angles, the two longer blades situated to one side and the two shorter blades to the other side of the pile, whereby said longer blades are adapted to securely engage the shorter blades of the adjoining pile when built up to form a wall.

9. Iron piling comprising a series of interengaging individual piles, of identical cruci-form transverse section, each pile have ing two pairs of longitudinal blades, one pair of which forming a female member and the other pair a male member.

10. Iron piling comprising a series of interengaging individual piles, of identical cruci-form transverse section, each pile having two pairs of longitudinal blades. one pair of which forming a female member and the other pair a male member: the female pair of blades having inwardly bent lflanges` 11. Iron piling comprising a series of interengaging individual piles, of identical cruci-form transverse section9 each pile having two pairs of longitudinal blades, one

pair of which forming a female member and the other pair a male member; the female pair of blades having inwardly bent flanges; said pairs of blades being oppositely disposed to each other on each side of a central plane and their blades forming continuai'nions of each other.

l2. lron piling comprising a series of interengaging individual piles, of identical eruci-orm transverse section, each pile having two pairs of longitudinal blades, one pair of which forming a female member and the other pair a male member; the female pair of blades having inwardly benlJ flanges; said pairs of blades being oppositely disposed to each other on each side oi a een` irai plane and 'their blades forming Contnuations oi.3 each other; the female memnoraeiebers of one individual pile engaging Jdie male members of the nearest individual pile, thereby securely locking the piles bo each other 1n order to form a continuous wall.

18. lron piling comprising a series of similar members, each essentially cross shaped in transverse secion, thereby providing on is opposite sides, pairs o symmetrically related blades; lehe blades on one side of each member being deflect/ed to provide an interlocking conformation with respect eo 'the blades on the opposite side.
